fatal runtime error: failed to initiate panic, error 5

[rcitsz]

The following command successfully compiles the result:

RUSTFLAGS='-C target-feature=+crt-static' cargo zigbuild --release --target aarch64-apple-darwin

However, at runtime, a panic in the program causes the process to exit. error: fatal runtime error: failed to initiate panic, error 5

If I compile directly on macOS without using zigbuild, it runs normally and a panic does not cause the process to exit:

RUSTFLAGS='-C target-feature=+crt-static' cargo build --release --target aarch64-apple-darwin

Why does the same code exhibit different panic behavior when compiled with cargo build versus cargo zigbuild?

The same issue occurs with x86_64-apple-darwin, where a panic causes the process to terminate:

RUSTFLAGS='-C target-feature=+crt-static' cargo zigbuild --release --target x86_64-apple-darwin

However, x86_64-pc-windows-gnu does not have this problem.

Thanks!

No idea, why use static crt? It’s not common to do that on macOS.

Whether it is dynamic linking or static linking, debug or release, I tried the following compilation commands and encountered the same issue: fatal runtime error: failed to initiate panic, error 5

cargo zigbuild --release --target aarch64-apple-darwin cargo zigbuild --target aarch64-apple-darwin cargo zigbuild --release --target x86_64-apple-darwin cargo zigbuild --target x86_64-apple-darwin

Nothing I can do here unless you can provide a minimal reproducible example.

fn main() {
    std::thread::spawn(|| {
        std::thread::sleep(std::time::Duration::from_secs(1));
        panic!("panic xxx");
    });

    loop {
        std::thread::sleep(std::time::Duration::from_secs(1));
        println!("continue...");
    }
}

compile using the docker image ghcr.io/rust-cross/cargo-zigbuild:latest： cargo zigbuild --release --target aarch64-apple-darwin

And then run the bin on my MacBook M1 Pro. Host info is: Darwin Kernel Version 24.0.0: Tue Sep 24 23:39:07 PDT 2024; root:xnu-11215.1.12~1/RELEASE_ARM64_T6000 arm64

But the Process terminated beacuse the panic. error: fatal runtime error: failed to initiate panic, error 5

If I compile directly on macOS without using zigbuild, it runs normally and a panic does not cause the process to exit: cargo build --release --target aarch64-apple-darwin

I need your help, thanks!
